OOASTING DEVICE.

Applintion filed March 20, 1985. Serial Io. 18,880.

To all whom it may concem:

Be it known that I, LOUIS Gonnsonmmr, a citizen of the United States,and a resident of Melrose Highlands, in the county of Middlesex andState of Massachusetts, have invented an Improvement in CoastingDeconnection with the accompanying drawings is a specification, likecharacters on the drawings representing like parts.

My invention relates to vehicular or like devices for coasting on snowor ice and adapted for use alike by adults or children for amusement,competitive sports, or conve ance purposes.

the drawings illustrating by way of example certain embodiments of myinvention:

Fig. 1 is a side elevation of a device em- 90 bogging one form of myinvention;

g. 2 is a plan view thereof; Fig. 3 is a vertical section, on a largerscale, taken along the line 3, 3 of Fig. 1; Fig. 4 is a cross section,upon a still larger scale, taken upon the line of Fig. 1,

looking down;

' 1g. 5 1s a view similar to Fig. 1, showing a modified constructionalso embodying my invention;

Fig. 6 is a plan of the device of Fig. 5.

The coasting, sledding or like device or apparatus of my invention maybe made in 1 various sizes ranging from those suitable for smallchildren up to those for use by adults. Referrin more particularly tothe drawings, an first to Figs. 1 to 4, the ,device there showncomprises a plurality of shoes, runners, or runner elements includinsggfront runner 1 and a rear runner 2.

front and rear runners may be identical in shape and size to facilitatemanufacture thereof in quantity, but preferably the rear runner issomewhat longer than the one in front, affording a larger supportingarea.

Said runners as illustrated have a skeelike formation includingup-turned portions or toes 3, 3 at the front ends and desirably one ormore longitudinal ribs 4, 4 upon their under surface, of general V-shapein cross section and serving to counteract side-slip of the device.

Said front and rear runners 1, 2, Figs. 1 and 2, are arranged in tandem,being connected by a suitable frame mounted thereon. Any strong andpreferably light material may be employed in f rm g the frame, such ascertain woods. or metals. Preferably, however, and as herein shown theframe is composed of a small plurality, of tubular metallic members ormetal tubes,

in concavo-convex or X-like. relation, and

connected at substantially the central portions of their curves, asby-the bolt or r1vet 9. The construction and arrangement of the tubularframe members as shown and described afiords a frame of great strengthand rigidity, and which is symmetrical and evenly balanced. Suchconstruction enables the device easily to be carried as by grasping itadjacent the point of connection 9 of the longitudinal tie members. Whenthere supported the weight of the device is substantiall equallydistributed to the front and to t e rear. It will be noted that thefront and rear posts 5 and 6 at their. lower portions are substantiallycontinuations of the line of curvature of the lower arcuate member 8 ortangential thereto whereby the frame is given an arch-like form ofmaximum strength consistent with lightness.

Mounted on the frame is a suitable seat,

10 desirably resiliently supported, herein b means of the seat post 11which extend downwardly within the upper end of the tubular rear 0st 6and rests upon a coil spring 12 having a suitable bearing support withinthe tube, herein rovided by a crosspin 13. Movement of t e seat islimited in any suitable manner, as b means of the lon 'tudinal slot' 14in t e rear post in which rides a pin 15 projecting radially from theseat post 11. Said seat is thus connected to the rear post but permittedto yield substantially vertically relatively thereto and at the sametime is prevented from objectionable transverse or turning movement.

The runners or runner elements-are attached at the lower extremities ofthe front and rear posts respectively in any suitable manner butpreferably in such we as to permit them to have a vertical roe g orpivoted movement, whereby the coasting deirregularities of the snow orice. Accordingly there is secured upon the upper surface of each of therunners 1, 2 a lock or lug 16, seen in detail in Fig. 3, and adapted forpivotal attachment to the frame. Desirably the rear runner 2 ispermitted only a vertical rocking movement relative to the frame. Therear post 6 is accordingly formed with a vertical, longitudinal slot atits lower extremity, within which the block 16 .of the rear runner isreceived. A pin or bearing 17 is passed transversely through said blockand the rtions or cars on 881d st at opposite s1des of the slot. Saidlock 16 is of a width substantially equal to that of the slot in therear post so as to have a close, workin fit therein when pivoting aboutthe pin 1 while said block and ears have sufiiclent longitudinal extentto prevent relative movement between them in a transverse or horizontalplane. The described construction is strong, simple and eflicient forthe purpose inten The front I'llIlIlBl'. 1 is preferably mounted forsubstantiall universal pivoted or rocking movement, being movable notonly vertically but also transversel for steerin purposes. As best seenin ig. 8, the bloc 16 of said front runner is pivotally secured, bymeans of a pin 18 and 1n a manner similar to that of the rear runner,between cars 19 at the lower end of a member 20 herein shown as a sleeveupon the u per end of which the front post 5 rests. aid member 20 isfast upon or formed integrally with the lower end of a steering post 21being herein secured thereto as by means of pins 22, 22; see Fig. 3.Said steering extends upwardly throu h the tubular front post 5 and isadapts to turn relatively thereto about its longitudinal axis. At its uper end said steering post is provided w1th suitable manual controlmeans, herein including a steering or handle bar 23 having the handgrips 24, 25.

Desirably the steerin movement of the front runner is limits toapproximately 180 degrees, 90 de ees to either side of its normal,straight nt position. For this purpose any suitable means may beemployed and herein I have shown a sto 26 WhlOh may be a. pin projectingradially m the steering post and adapted to brm up against the shoulders27, 28 on the out post 5 at one or the opposite limits of the steeringswing desired for the front runner. Said pin 26 also serves to hold thesteerin post and front tubular post in assembl position when the deviceor vehicle is being carried.

To assist the operator in mounting the coaster a mounting step 29, Figs.1 and 2, may be provided at the rear portion of the frame, while at a.convenient point at the front of the latter a suitable foot-red; 30

may be provided, to support the feet of the operator, when desired.

In Figs. 5 and 6 I have shown a ooasti device. also embodying myinvention an which 1n all respects not otherwise mentloned may be thesame as that of Figs. 1 to 4. As illustrated in Figs. 5 and 6 the deviceor apparatus is self-supporting, that tudinal tie member 8 joins it,there is se cured a cross bar 31. Upon the opposite ends of said crossbar are mounted runners 32, 33 which in detail may be the same as therear runner 2 of Figs. 1 to 4. Said cross bar 31 desirably terminates atits 0 posite sides in portions 34, 35 extending su stantially at rightangles to the plane of the runners, so as to permit free verticalrocking movement of the latter. Said cross bar may also serve as.amounting step, in which case the ste 29 may be omitted. Obviously, ifdesire and within the scope of my invention, the front runner elementmay also be double, or other arrangement and number of runners emplo ed.

From the foregoing it w1ll be understood that the vehicle, coaster orwinter-sports device embodg ing my invention comprises a pluralit 0runner elements connected by a suitab e strong, light frame desirablysupporting a seat for the operator or rider.

referably the runners are individually rockable vertically relative tothe frame, while the front runner or runners are in addition capable ofpivoted movement transversely of the frame, for steer' purposes,although in some instances, as m coasting upon prepared slides such(provision for steering need not be employe My invention is not limitedto the specific embodiments thereof shown and described herein.
